Even though this was such a Really Good Masterpiece which Made me cry again and again every time I re-read this, especially chapter 12 until 17, the one about Aka. What a shame the manga got axed, i hope the LN won't
Just read all the chapters real quick, and the story goes.. literally nowhere. The final chapter went the same as pretty much every other chapter. It's just a fanservice comic, and not even good fanservice. Avoid this.
I hope you are right, but can't recall any such manga getting that treatment unless you are referring to a remake of this.
